Tether wallet freezes reduced Iran-linked USDT transaction volumes by 94%, Chief Executive Paolo Ardoino claimed on October 19, 2026, as the stablecoin issuer challenged US Senate investigators’ criticism of its sanctions compliance. Tether has not publicly disclosed the underlying transaction data, measurement period or methodology, leaving the claimed reduction unverified.
Key Takeaways
- Tether’s claimed 94% reduction lacks publicly disclosed data and a measurement period.
- Senate investigators questioned whether the company froze sanctioned wallets quickly enough.
- Freezing USDT can immobilize tokens, but does not establish a matching decline in overall illicit activity.

Tether wallet freezes: what the 94% claim establishes
Ardoino’s statement presents a company assessment of enforcement effectiveness, not an independently verified measure of declining illicit finance. Without a defined measurement period or methodology, readers cannot determine which transactions were counted or how the reduction was calculated.
Ardoino also said that, since 2023, Tether had frozen relevant addresses an average of four weeks before formal designation by the US Treasury’s Office of Foreign Assets Control or Israel’s National Bureau for Counter Terror Financing. He claimed Tether acted before blockchain analytics firm Chainalysis identified the addresses in 99% of relevant cases.
These timing claims form part of Tether’s rebuttal to allegations that it allowed some wallets associated with sanctioned entities to remain operational too long.

Senate investigators challenge the speed of enforcement
A September 28, 2026, report by Democratic staff of the Senate Permanent Subcommittee on Investigations examined 846 cryptocurrency wallets sanctioned or targeted for seizure between June 2021 and August 2026 over connections to Iran or its regional proxies.
Investigators found that 84% of those wallets transacted exclusively or almost exclusively in USDT. That finding describes the assets used by the wallets examined; it does not measure Tether’s effectiveness in stopping their activity.
In one case involving wallets linked to Hezbollah financier Tawfiq Muhammad Sa’id Al-Law, investigators alleged that more than $34.6 million in USDT moved from addresses before Tether completed freezes. Senator Richard Blumenthal subsequently requested Treasury and Justice Department investigations into Tether’s sanctions compliance practices.
Tether disputes the characterization of its enforcement record and emphasizes its cooperation with law enforcement. The requests for investigations do not themselves establish a regulatory finding against the company.
Frozen assets and reduced transaction flows are different measures
Tether’s September 28 enforcement statement described freezes involving wallets that US authorities had identified as connected to Iran’s central bank and sanctions networks. Those disclosures concern the value of immobilized assets, rather than the transaction-volume measure behind Ardoino’s later 94% claim.
USDT has issuer-controlled functionality that can stop designated addresses from transferring tokens. That provides an enforcement tool, but cannot prevent transfers that occur before an address is identified and frozen.
A decline in Iran-linked USDT transactions would also not establish an equivalent decline across all cryptocurrencies if users moved to other assets or networks. The distinction matters when assessing whether enforcement restricted illicit finance overall or changed which payment channels were used.
Conclusion
The dispute turns on both the speed of wallet freezes and how their effectiveness is measured. The next issue to watch is whether Tether releases supporting transaction data or authorities publish findings in response to the requested investigations.
